Alarms
Open coldroom door alarm (controller type UR 141)
Alarm is generated if the coldroom door remains open beyond a definable time (Menu 6−2−3).
High or low temperature alarm
High or low temperature is alarmed when temperature rises or falls to the alarm setpoint on the supply air sen-
sors (UA 111 X / UA 111 XP) or room air sensors (UR 141) and the set delay has expired.

The high temperature setpoint is entered in
°
C, whereas the low temperature setpoint is entered as a difference
to the cooling setpoint in K. High and low temperature setpoints can be set separately for each temperature
zone. The time delay applies to all.
This alarm is inactive during defrosting. Any delay that may have started is reset at the commencement of defro-
sting and restarts from the beginning on completion of defrosting.
No defrost alarm
Alarm is generated if defrosting does not take place during a definable interval, but not if defrosting is suppres-
sed due to high temperature or by demand defrosting.
The delay for the
No Defrost
alarm should not be set too small so as to avoid false alarms (
No Def-
rost
parameter
in
Menu 6−2−3). If the maximum interval between set defrost times (Menu 3−2) is 48
hours, for example, the delay for
No Defrost
alarm must be set at least 1 hour longer, i.e. 49 hours
